Application filed March 10, 1920.

T a l Quiz-om mag canoe r 12 Be it known that I, Crrnsrnr. Fianna, acitizen of the United States. residing at Seattle, in the county of Kingand State of Washington, have invented. certain new and use fulImprovements in lVorlcHolding Stands, of which the following is aspecification.

This invention relates to stands which are des'gned, more especially,for reversibly holding automobile engines or the like while beingoperated upon in a shop. The object of" my invention is the provision ofa device of this character which will he of inexpensive, strong anddurable construction. and which is adapted to be readily adjusted toaccommodate various sizes of engines, and is convenient in use.

The invention consists in the novel construction arrangement andcombination of parts as vill be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevational view of astand embodving my invention shown applied.

Fig. 2 an end elevation of the same with the work and bracket supportstherefor in positions reversed from where they are represented in Fig.1.

Fig. 3 is a horizontal section through 3-3 in. l.

n l is a detail transverse sectional view of one of the bracketconnections with a side member or" the stand.

5 is a sectional view taken substantially through 55 of Fig. 2, withparts broken away.

Fig. 6 is a perspective view of a rail attachment for a stand bracket.

Fist. 7 is a fragmentary elevational view of one of the side members ofthe stand.

According to the present invention I provide a stand having twocomplementary frames 10 and 10 each of substantially the shape of anisosceles triangle formed of sheet steel to provide a central webportion 11 and marginal flanges 12 at the sides and extendingover theupper angle.

To each ot the lower corners of the frame is secured as by rivets 13 theflange element 1-il ot a chambered casting: 15 through which ext nds anaxle 16 for a ground wheel or roller 17.

Extending transverselv through the frame webs and the respective flanges14: are parallel bars. such as pipes 18. which are rigidly secured tothe frame 10 by nuts 19 engpecification of Letters Patent.

gaging pipe threads at opposite sides of the name as shown in Figs. 3and The pipes 18 are adjustably connected to the other frame 10 byslidablv fitting in bosses or sleeve elements 20 of the respectivecastings and secured by set-screws 20 for retaining toe frames atselected distances apart.

Rig-idly secured within the spaces afforded by the frame flanges 12 atthe upper angle oi? the respective frames are apertured blocks. as 22serving as hearing; boxes for screw bolts 23 and 23 which support hangerblocks 2t and 24 one to the inner side of each frame. The hanger blocl:24 is provided with tongues or projections 25 (Fig. adapted to engage inslots 26 extending radially from the bolt receiving aperture 27 of theadjacent bearing block 22 (Fig. 7) for retaining the hanger blocks inrotary adjustments.

Such engagement of the said tongues and grooves are effected b v meansof the bolt 23 and nut 28. This bolt 23 is prevented from turning bysoclretinr; its polvgonal head 23 in a correspondingly shaped recess 24provided in the associated block 22. The nut 28 for bolt 23 is desirablvprovided with a lever handle 28 to facilitate the turning of the same.The nut 29 for the other bolt 23 may also be provided with a similarhandle, or as shown. he of ordinary construction to be. tightened orloosened through the medium of a suitable wrench.

30 represent angle bars secured to the lower ends 2) of'the hangerblocks 24 and 24 by bolts 31 passing: through holes 32 provided on thebar flanges 30 The other bar flane'es are desirably formed withlongitudinal slots -3 to accommodate bolts 34 for clamping plates 35between which and the adjacent bar flaneies 30 the flanges as A. oi"? anengine block B mav be secured. E or operation. the stand is wheeled onits rollers 17 to the place whereat an engine block at B is to bereceived and which block is placed upon the bars 30 when the bannerblocks 2- l-2at are pendent as shown in Figs. 2.

The work thus supported upon bars 30 is T then secured thereto with itsflanges A below the clamping plates 35 by means of bolts 3 Anyoperations to be done upon the work, such grindi valve seats etc. whichmay be most conveniently performed with the the worlr upright isaccomplished with the Cir work and supporting parts therefor in thepositions in which they are illustrated in F 7 When the work is to beoperated upon from the sides or bot-tom it may be brought into inclinedor reversed positions, as inclicated in Figs. 1 and 4, by rotatablymoving the same about the axes of bolts 23 and E23 and secured inselected positions by utilizing the respective nuts 28 and 29. The widthor space between the work supporting bars 30 is regulated to correspondwith the widths of various engine blocks by regulating the position ofthe frame 10 with respect to the frame 10 by first loosening set screws21 and then moving the frame 10 longitudinally of the pipes 18 and,

finally, securing the frame 10 to said pipes by means of the set screws.

The 0 aeration and advanta es of the mvention wlll be understood fromthe foregoing descrlption. 7 L I lw hat I claim, is-

A worlcholding stand of the character de scribed comprising, 111combination, a pair of frames, a pair of bars extending through thelower portions of said frames, means for securing said bars to theframes to retain the latter in different positions of ad justment;apertured bearing blocks rigid with the upper ends of said frames, oneof said blocks being provided with recesses dis posed radially of theblock aperture, worksupporting blocks, means for securing work thereto,bolts extending through apertures of the bearing blocks and thesupporting blocks for pivotally connecting the supporting blocks to therespective frames, and a tongue provided on one of said supportingblocks and engaging in selected of the aforesaid recesses for retainingthe respective supporting block in various predetermined rotarypositions.
